About Caverta
Caverta is a brand-name tablet of sildenafil, a phosphodiesterase-5 (PDE-5) inhibitor that has been approved worldwide for the treatment of erectile dysfunction (ED). In Singapore the medication is prescribed when a man experiences difficulty achieving or maintaining an erection sufficient for satisfactory sexual activity. The 100 mg pill is taken as needed, typically about an hour before intercourse, and its effects can last up to 12 hours. While the primary indication is ED, the same compound is sometimes employed off-label for other vascular conditions, a point that will be discussed later. Understanding how Caverta works, what makes it appropriate for certain patients, and how to use it safely can help men make informed choices about their sexual health.
What is Caverta?
Caverta is a branded formulation of sildenafil citrate, marketed by a well-known pharmaceutical company that produces a range of cardiovascular and urological medicines. As a brand product, it contains the exact 100 mg dose of sildenafil in a film-coated tablet designed for rapid oral absorption. Sildenafil belongs to the class of PDE-5 inhibitors, a group that also includes other agents such as tadalafil and vardenafil. The molecule was first synthesized in the early -s and gained regulatory approval for ED in the mid--s after large-scale clinical trials demonstrated its efficacy and safety. In Singapore, Caverta is a prescription-only medicine, reflecting the need for a medical assessment before use. Generic sildenafil tablets, which contain the same active ingredient, are available at lower cost and are considered bio-equivalent, but the branded product may be preferred by patients who seek a known quality standard or who have specific insurance coverage for the brand name.
How Caverta Works
Sildenafil exerts its effect by blocking the enzyme phosphodiesterase-5, which normally degrades cyclic guanosine monophosphate (cG c) in the smooth muscle cells of the penile vasculature. During sexual stimulation, nitric oxide (NO) is released from penile nerves and endothelial cells, activating guanylate cyclase to convert guanosine triphosphate (GTP) into cG c. The rise in cG c relaxes smooth muscle, allowing blood to fill the corpora cavernosa and produce an erection. By inhibiting PDE-5, sildenafil sustains higher cG c levels, prolonging smooth-muscle relaxation and facilitating the inflow of blood.
After oral ingestion, the tablet dissolves quickly, and sildenafil reaches peak plasma concentrations within 30-60 minutes. The drug’s half-life is approximately 4 hours, which accounts for its ability to support sexual activity for up to 12 hours after a single dose. Metabolism occurs primarily via the hepatic cytochrome P450 3A4 pathway, with renal excretion of inactive metabolites. Because the onset and duration are closely linked to the drug’s pharmacokinetic profile, timing the dose about an hour before anticipated intercourse optimizes the therapeutic response while minimizing the risk of residual blood-level effects later in the day.
Why Caverta Is Used for Sexual Health Conditions
-
Restoring physiological erection: In men with ED, the underlying problem is often insufficient NO-stimulated cG c production or premature degradation of cG c. By preserving cG c, Caverta directly addresses the biochemical deficit, enabling the natural erectile process to proceed when sexual stimulation occurs. Clinical trials involving thousands of participants have shown that a single 100 mg dose improves erection rigidity in roughly 70 % of men compared with placebo.
-
Improving confidence and relationship satisfaction: Erectile function is closely tied to psychological well-being. When a medication reliably supports sexual performance, many patients report reduced anxiety and enhanced intimacy with their partners. This psychosocial benefit, although not a pharmacological effect, emerges from the drug’s ability to reliably produce an erection when needed.
-
Compatibility with other cardiovascular medications: Because sildenafil’s primary action is localized to penile tissue and its systemic blood-pressure effect is modest, it can often be co-administered with antihypertensive drugs, provided that contraindications (such as concurrent nitrate therapy) are observed. This makes Caverta a viable option for men with co-existing heart disease who require ED treatment.
-
Evidence-based guideline endorsement: International urology societies, including the American Urological Association and the European Association of Urology, place PDE-5 inhibitors as first-line therapy for most cases of ED. The recommendation stems from large-scale randomized controlled trials that consistently demonstrate superior efficacy and tolerability of sildenafil relative to placebo and to older interventions such as intracavernosal injections.
Off-Label and Investigational Uses of Caverta
Sildenafil’s vasodilatory properties have prompted investigation beyond erectile dysfunction. In pulmonary arterial hypertension (PAH), the drug is approved under the brand name Revatio, but some clinicians in Singapore prescribe Caverta off-label for patients with milder forms of PAH when the approved formulation is unavailable. Small studies suggest that sildenafil can lower pulmonary artery pressure and improve exercise capacity, though the evidence remains less robust than for dedicated PAH agents.
Another explored indication is Raynaud’s phenomenon, a condition where peripheral blood vessels constrict excessively in response to cold or stress. Preliminary trials report modest improvement in digital blood flow after sildenafil administration, yet larger, controlled studies are needed before widespread adoption. Off-label use only under qualified healthcare provider supervision.
Is Caverta Right for You?
Caverta is best suited for adult men who have a confirmed diagnosis of erectile dysfunction and who are not taking nitrate-containing medications. Patients with severe uncontrolled hypertension, recent myocardial infarction, or significant liver impairment may require alternative therapies, as such conditions heighten the risk of adverse cardiovascular events. Men with mild renal dysfunction generally tolerate the 100 mg dose, although dose adjustment might be considered by the prescribing physician.
Contraindications-such as concurrent nitroglycerin use-are critical because combined vasodilation can precipitate dangerous drops in blood pressure. Similarly, individuals with a known hypersensitivity to sildenafil or any tablet excipients should avoid the medication. For patients over 65, or those with concomitant use of strong CYP 3A4 inhibitors (e.g., ketoconazole), clinicians often start with a lower dose to mitigate potential drug-interaction effects. Ultimately, the decision rests on a comprehensive medical assessment that weighs the benefits of restored erectile function against any cardiovascular or pharmacologic risks.
Taking Caverta Effectively
To achieve optimal results, take the tablet with a glass of water about 30-60 minutes before sexual activity. Food can delay absorption, particularly high-fat meals, so a lighter snack may be preferable if timing is critical. While the usual recommended dose is 100 mg, the prescribing physician may adjust the amount based on individual response and tolerance. If a dose is missed, do not double-up; wait until the next planned occasion. Consistency in timing helps maintain predictable plasma levels and reduces the likelihood of unexpected side-effects.
Avoid excessive alcohol consumption, as it can impair erection quality and amplify potential dizziness. Smoking cessation also supports vascular health, enhancing the drug’s efficacy. For men traveling across time zones, maintain the same interval between dose and anticipated activity rather than adhering to a strict clock time. Setting reminders on a smartphone or using a medication-tracking app can improve adherence, especially when the medication is used on an as-needed basis rather than daily.
Understanding Side Effects and How to Manage Them
The most common adverse events arise from the drug’s vasodilatory action. Transient facial flushing, mild headache, and a sensation of nasal congestion often appear within the first hour after ingestion. These effects are typically self-limiting; staying hydrated and resting in a cool environment can alleviate discomfort. Headache may respond to an over-the-counter analgesic such as acetaminophen, provided no contraindications exist.
Occasionally, patients experience visual disturbances, such as a temporary blue tint to vision or increased light sensitivity. These changes reflect sildenafil’s minor inhibition of PDE-6, an enzyme involved in retinal phototransduction. If visual symptoms persist beyond a few minutes or are accompanied by pain, seek medical evaluation promptly.
More serious, though rare, complications include sustained erections lasting longer than four hours (priapism) and sudden drops in blood pressure leading to dizziness or fainting. Immediate medical attention is warranted for priapism, as prolonged erection can cause permanent tissue damage. Signs of severe hypotension-such as faintness, blurred vision, or syncope-should also prompt urgent care, especially if the patient has taken nitrates or other potent vasodilators.

Frequently Asked Questions
-
How soon after taking Caverta can an erection be achieved? Typically 30-60 minutes after ingestion, provided that sexual stimulation occurs. Food, especially a high-fat meal, may extend this window slightly.
-
Can I take Caverta more than once a day? The medication is intended for single-dose use per sexual encounter. Taking another dose within 24 hours increases the risk of side effects without additional benefit.
-
What should I do if I experience a prolonged erection? A erection lasting longer than four hours (priapism) constitutes a medical emergency. Seek immediate care; early intervention can prevent permanent tissue damage.
-
Is it safe to use Caverta with alcohol? Moderate alcohol consumption does not contraindicate use, but excessive intake can impair erectile response and heighten dizziness. Limiting alcohol to one or two drinks is advisable.
-
Will Caverta affect my blood pressure? Sildenafil may cause a modest reduction in systemic blood pressure, particularly when combined with other vasodilators. Patients with uncontrolled hypertension should discuss usage with their physician.
-
Are there any interactions with common heart medications? Nitrate drugs (e.g., nitroglycerin) are absolutely contraindicated due to synergistic vasodilation. Other cardiovascular agents, such as beta-blockers or ACE inhibitors, are generally compatible, but dose adjustments may be needed.
-
How does Caverta compare to other ED pills like tadalafil? Sildenafil has a shorter half-life (≈ 4 hours) compared with tadalafil’s 17-hour duration, making Caverta more suitable for on-demand use. Tadalafil may be preferred for patients seeking a longer therapeutic window.
-
Can women use Caverta? Sildenafil is not approved for female sexual dysfunction and lacks sufficient safety data in women. Off-label use in females is discouraged.
-
Will taking Caverta affect my fertility? Current evidence indicates no impact on sperm count or quality. The drug acts locally in penile tissue and does not influence hormonal pathways related to fertility.
-
Is it necessary to have a prescription to buy Caverta online? Yes. Our service requires a valid prescription from a licensed healthcare professional before dispensing the medication, ensuring safe and appropriate use.
-
What should I do if I miss a dose? Since Caverta is taken as needed, simply wait until the next occasion. Do not attempt to double the dose to compensate for a missed administration.
Glossary
